Having issue's with Samsung BD-P1400

[neos_peace]

Ok first off if this has been posted before sorry. I did a small search and my issue I couldn't find.

OK now on to my thing.

I have a Samsung BD-P1400. I have 16 BD titles so far. Now some titles like the one I just got Underworld Evolution loads perfect plays perfect and has an awesome responce time. Now others like a movie I just rented on BD "Bee Movie" loads up pretty well but stops after 3 1/2 minutes of play. I have the latest firmware june 20th. Now someone had said before I need to update my receiver (meaning get a better one) But most of my titles play perfect, some taking a bit to load but otherwise play fine.
I guess my question is this why do most titles play good while others just don't want to cooperate with me (HP order of the pheonix doesn't want to play, while I just watched the eye and it played flawlessly.) Could there be some issue that the firmware is not addressing. What are you fellow fans thougths on this prolly common issue. Any help is thanked.
